Palnadu is a district located in the Indian state of Andhra Pradesh. It was carved out of Guntur district and became a separate administrative unit on 4 April 2022 as part of the state's reorganisation. Narasaraopet serves as the district headquarters.

Palnadu is historically significant as the site of the Battle of Palnadu, which took place in the 12th century between rival factions of the Haihaya dynasty. The conflict is noted in regional folklore and literature, including the Palnati Vira Charitra.

The district is located in western Andhra Pradesh and features a mix of low hills, rocky terrain, and agricultural plains. It has deposits of minerals such as limestone and granite, particularly in the Macherla and Dachepalli areas. The Krishna River and its canal systems provide irrigation to much of the region.

According to data adapted from the 2011 Census of India, the district has a population of approximately 2,041,723.

The population is mostly rural, with agriculture being the primary source of livelihood. Telugu is the most widely spoken language, followed by Urdu and Lambadi in certain areas.

The district has religious and cultural sites of significance. Amaravathi is a site of religious importance for both Hindu and Buddhist communities. The Amareswara Temple attracts devotees during Maha Shivaratri, while the nearby Amaravati Stupa and Dhyana Buddha statue represent the area's Buddhist heritage.

Other notable locations include the hill shrine of Kotappakonda, which hosts the annual Tirunalla festival. Traditional martial arts such as karra-samu (staff fighting) and kathi-samu (swordplay) are performed during some rural festivals.

Agriculture forms the basis of the district's economy. Main crops include cotton, chillies, tobacco, and paddy. Irrigation is largely sourced from the Krishna River. Mining, particularly of limestone and granite, is present in mandals such as Dachepalli and Macherla.
